Scholl Verruca and Wart Complete Treatment Pen is an easy, effective treatment for verrucas and warts on hands and feet, suitable for children from 4 years old**. It contains TCA-Active™ for clinically proven treatment, and its precision tip and one-click action deliver a coloured treatment so you can see exactly where you have applied it and avoid healthy skin. Treatment takes 4 days, with visible results in 1 week. Hold the pen vertically and press the button until the treatment comes out, apply one drop of the blue treatment to the verruca or wart, and let it dry for 10-15 minutes. Store in the original packaging at room temperature (15-25°C); once opened, use within 6 months and do not use after the expiry date on the pen and box. Pack Contents 1x pen. Safety Warning Do not use if the skin is not intact, if you are unsure whether the condition is a verruca or wart, or if you are hypersensitive to any ingredient. Do not use on skin tags, moles, dark patches, freckles, water warts (mollusca contagiosa) or seborrhoeic keratosis. If gel touches healthy skin, wash immediately with plenty of soap and water to prevent irritation or burning. Not suitable if you have diabetes or poor blood circulation – consult a doctor or podiatrist first. Keep out of the sight and reach of children.
